Your new DKLP unit is a high quality, commercial grade,
programmable digital key control station. The unit is designed to operate at
extremely low current and therefore is perfect for solar applications or conditions which
require very little current draw. The unit incorporates a double pole double throw
relay which includes a set of latch contacts for activation of a device and a set of alarm
shunt contacts for activation of an external alarm. Both sets of contacts employ
both a normally open and normally closed output. The DKLP is housed in a 16 gauge
steel enclosure with a powder coat finish for durability and also includes a stainless
steel faceplate with metal keypad. Please be sure to read and understand all
instructions before proceeding with the hookup and programming instructions.

BEFORE PROCEEDING

To take full advantage of the 24
month limited warranty, you must be registered with American Access Systems,
Inc. Please read the enclosed warranty statement, fill out the warranty registration
card provided and sent it to:

Make sure to have all the tools listed. Upon opening
the box, check off the items enclosed with the unit. If any items are missing from
your unit, contact American Access Systems immediately.

Mounting the unit to your own pedestal

Your unit comes with a square mounting flange found in the
bottom of the box along with four carriage bolts and four hex nets. The square
mounting flange may be welded to your pedestal and flange bolt pattern will align with the
back of the unit. Place the unit up to the flange and insert the carriage bolts from
the back side. Secure the unit to the flange by tightening down the hex nuts with a
7/16" socket.

Mounting the unit to an AAS gooseneck (AAS-PAD)

Locate the four carriage bolts and four hex nuts found inside
the unit box. Place the unit up to the pedestal flange and insert the four carriage
bolts from the backside. Secure the unit to the pedestal using the four hex nuts
and a 7/16" socket. The extra square mounting flange may be discarded.

HOOKUP STEPS

(A) Your DKLP control unit operates on 6 to
14 volts DC. Measure the voltage from the power source to make sure it falls within
these tolerances. Locate the Red and Black wire on the ACU HARNESS and with the
power off connect Red to positive (+) and Black to negative (-).

NOTE: If you are using the optional AAS-9VDC
transformer, cut the end connector from the transformer and discard. Using
appropriate wire nuts, connect black to black and black/white to red.

(B) Connect the device to be
controlled to the appropriate control leads of the ACU HARNESS.

(C) Double check your
connections. When you are sure that everything is hooked up correctly, apply power
to the unit. A BEEP should be heard when you press a key on the keypad.

THE IDLE MODE

The idle mode is the normal mode of operation. When in
this mode the unit sits and waits for data from the keypad. If a key is pressed from
the keypad, you will have approximately 3 seconds between each keypress before the unit
resets.

THE PROGRAM MODE

the program mode is the mode of operation in which you will
enter/change your access code. The program mode is accessed by pressing and then
releasing the PROGRAM/RESET located on the DKLP circuit board. In this mode you will
have approximately 15 seconds between keypresses. If this time is exceeded, the unit
will exit the program mode and return to the idle mode.

PROGRAMMING

A person desiring to change their access code will open the
face of the unit and locate the PROGRAM/RESET button on the DKLP circuit board. The person
will then press and release the PROGRAM/RESET button. The unit will beep once.
The person will then enter their new 4 digit access code from the keypad. the user
will then be prompted with a beep to enter the relay output time in seconds from 1/2
second to 9 seconds. Note: "0" = 1/2 second. If you
make an entry error, simply press either the * or # key and re-enter the correct
data. After the code is programmed the unit will return back to the IDLE MODE.

EXAMPLES:

To set the access code to 1234 with a relay output time of 5
seconds, press the PROGRAM/RESET button and enter: 1 2 3 4 then enter 5

To set the access code to 7890 with a relay output time of
1/2 seconds, press the PROGRAM/RESET button and enter: 7 8 9 0 then enter 0. Note
"0" = 1/2 second
